4 the purpose of warning drivers that they are approaching danger in the form of curves, schools, hills, intersecting streets, or the like. An important object of the invention is to 'provide a danger signal that is operative either durin daylight hours or after dark for accompl shing the purpose set forth above.

A further object of the invention is to rovide a trafiic signal of such a nature-that 1t will, with great certainty, attract the attention of all drivers for warning them of the approach of danger on the streets or highway they are traveling over.

Other objects and advantages of the invention will be apparent durlng the course of the following description In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a front elevational view of the signalling device embodying this invention,

Figure 2 is a front elevational view of the device shown in Fig. 1 with the door forming a portion of the front wall of the .same in its open position to better enable the contents of the casing to be seen, and Figure 3 is a vertical sectional view, partly broken away of the signal casingembodying this invention and shown in Figs, 1 and 2.

In the drawing, wherein for the purpose of illustration is shown a preferred embodiment Ofthis invention, the numeral 5 de'signates a post of a a standard having an enlarged base 6 suitably connected thereto for the purpose of allowing the device to be secured to a road or sidewalk, the said post being provided at 7 its upper end with a collar 7 that is adapted for being suitably secured to the lower arcaate wall 8 of the signal casing which further Eonsists of a rear wall 9, side walls 10, a relatively small rigid front wall 11 and a lnngedly connected door 12 that forms the substantial portion of the front wall of the casing. This door 12 is suitabl to-one side wall 10 by means 0 the hinges 13 and is also provided with a clasp or looking element 14 that is adapted for coacting with the locking element 15 carried by the opposite side wall of the casing 10 for the purpose of retaining the said door in its closed locked position.

Suitably secured to the rear wall 9 of the said casing are a pair of spaced brackets 16 and 17 which are adapted for supporting a perpendicular shaft 18 that is suitably journaled in bearing portions of the said bracket. Spaced laterally of the perpendicular shaft 18 is an electric motor 19 which is suitably supported by a bracketmember 20 secured to the rear wall 9 of the casing. The armature shaft 21 of thiselectric motor is provided with a bevel pinion 22 which is constantly in mesh with a bevel gear 23 suitably keyed to substantially the lower end of the perpendicular shaft 18 for'the purpose of rot-atlng the said shaft when the said motor 1s supplied with current by the electric wires '24:. Referring particularly to Fig. 3 wherein there is shown a horizontally extending post 25 that is rigidly connected, as at 26 to the rear wall 9 of the casing as shown. Loosely mounted upon the perpendicular shaft 18 is a sleeve 27 that is provided with upwardly extending arms 28 having bearing portions 28 formed at their extreme outer ends which are adapted for encircling sleeves 30 rot-atably mounted upon the horizontal post 25 and provided with beveled gears 31 upon their inner ends. These beveled gears 31 are constantly in mesh with a beveled gear 32 suitably keyed to the extreme upper end of the perpendicular shaft 18 and engaging the same on diametrically opposite sides.

The sleeve members 30 are each provided 3W with a pair of oppositely extending radial spokes 33 which are-suitably'connected at their outer ends to signalling disks A, B, C, and D, as best indicated in Fig. 3. These disks A, B, (Land. D are preferably all of di'fierent colors such as red, blue, green, and white. a

In this showing of the invention, the door 12 is provided with a series of letters 34: that are-formed by properly perforating the said connected 6'0 door as best shown in Fig. 1. Secured to which is provided with a reflector 37 adapted for throwing the rays of light upwardly to illuminate the disks and the perforated letters carried by the said casing. This electrio bulb 36 is supplied with current from the electric wires 24 by branch wires 24; as best shown in Fig. 2. It is to be understood 'that this application is not limited to words formed by imperforating the ,door 12 for the said danger indicating words may be painted ,upon the front face of the same whereupon an electric bulb '36" and reflector-37 may be mounted outwardly of the casing upon the relatively small rigi front wall 10, as shown in dotted lines in ig. 1. The operationof the device is as follows:

When, current is supplied to the electric motor 19, the perpendicular shaft 18 will be rotated due to the gear connection formed with the armature shaft 21. The rotation of the perpendicular shaft 18 will cause the spokes 33 carried by the rotatable sleeves 30 to rotate in opposite directions. due to the position of the bevel gears. 31 on diametrically opposite sidesof the bevel gear 33 carried by said perpendicular shaft. This rotation of the sleeves 30 in opposite direc tions will cause the disks 0 and D to move on an arcuate path above the upper open end of the casing starting from the left hand side of the same and disappearing within the casing on the right hand side. The two remaining disks A and B will be caused to move through an arcuate path above the said casing in an opposite directionto the movement of the disks C and D the-said disks are intended to occur when the disks C and D are positionedin their full line showing as in Fig. 2. The other two disks A and B being at thistime directly in line with the disks C and D or in other words positioned directly rearwardly of the same. The second passing point will occur when the disk 0 has been moved into the position shown in dotted lines atthe left hand side of the casing in Fig. 2. This movement of the disks in opposite direc: tionswill tend to indicate that there is-but one d1sk moving on arcuate paths in opposite dlrections above/the casing, the said d1sk changing in color'as it changes the direction of movement from-the right to the left or vice versa. I

This to be understood that the'form of this invention herewith shown and described masses is to be taken as the preferred example of the same, and that Various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjo'ined' claims. Obviously, a -weight,

spring or other form of motor may\be substituted for the electric motor 19, while the discs A, B, C and D may be in the form of lamps or electrically illumined if desired. Having thus described the invention, ll claim 1.

10. In a signal apparatus, a casing, a series of signalling members rotatably supported within said casing adapted to travel arcuate paths exteriorly of the same appearing and disappearing fro-m opposite sides thereof, said members being divided into two groups with the members of one group traveling in a direction opposite to that of the other group, and means for rotating said members so'that there will appear to be' 'only one member reversely traveling in an arcuate path exteriorly of said casing.
